Add scenario reports and artifact policies

[slideep]

Summary

• add JSON and JUnit scenario run reports for run --file and run --path
• add artifact attachment and failure-capture policy controls
• preserve deterministic scenario IDs, shard metadata, terminal events, and report output across planning and execution failures
• cover recursive glob discovery, hash sharding, JUnit artifact output, report failure shapes, and malformed scenario validation

Validation

• dotnet test Luotsi.Cli.Tests\Luotsi.Cli.Tests.csproj
• dotnet build -c Release
• git diff --check

[Copilot]

Pull request overview

Adds first-class scenario run reporting (JSON + JUnit) and introduces new controls for failure artifact capture and report artifact attachment, while extending scenario path resolution (recursive globs) and sharding (stable hash strategy). This fits into the CLI scenario execution pipeline by wrapping planning/execution with report/event coordinators and enriching scenario identity metadata for correlation.

Changes:

• Add JSON and JUnit scenario run reports for run --file / run --path, including failure-shape preservation across planning/execution errors.
• Add artifact policy controls: --capture-on (failure artifacts generation) and --attach-artifacts (report attachment policy), plus deterministic scenario_id propagation in events/results.
• Add recursive glob discovery (**/*.json) and --shard-strategy index|hash for stable sharding.
